RCW 63.29.130

Property held by courts and public agencies—When abandoned—Overpayments.

Intangible property held for the owner by a court, state or other government, governmental subdivision or agency, public corporation, public authority, or the United States or any instrumentality of the United States that remains unclaimed by the owner for more than two years after becoming payable or distributable is presumed abandoned. However, courts may retain overpayments made in connection with any litigation, including traffic, criminal, and noncriminal matters, in an amount less than or equal to ten dollars. These overpayments shall be remitted by the clerk of the court to the local treasurer for deposit in the local current expense fund.
